Description

A kind of pyridyl indenofluorene compounds and application
Technical field
The present invention relates to a kind of novel organic materials, and the application in the ORGANIC ELECTROLUMINESCENCE DISPLAYS technical field.
Background technology
As a rule, electron transport material all has the plane aromatics of large conjugated structure, they mostly have and connect preferably nucleophobic ability, under certain forward bias, can effectively transmit electronics again simultaneously, at present known well behaved electron transport material is also few, available electron transport material mainly contains oxine aluminium compounds at present, the furodiazole compound, quinoxaline compound, the polymkeric substance of nitrile group-containing, (the Chem.Mater.2004 such as other nitrogen-containing heterocycle compound, 16,4556-4573, J Mater.Chem.2005,15,94-106).
Therefore will design an electron transport material that organic electroluminescence device efficient is significantly promoted, need possess following character: (1) has reversible electrochemical reduction and enough high reduction potentials; (2) need to there be suitable HOMO and LUMO to make electronics that minimum injection energy gap be arranged, to reduce initial and operating voltage; (3) higher electron mobility need to be arranged; (4) has the stable and thermostability of good gamma transition; (5) has noncrystalline film.(electroluminescent organic material and element, the prosperous yellow filial piety literary composition of Chen Jin work, five southern bibliogony companies).
Summary of the invention
The objective of the invention is to propose a kind of novel cpd, this compounds can be used for the ORGANIC ELECTROLUMINESCENCE DISPLAYS field.
Thereby having large conjugate planes structure, the derivative of indenofluorene can provide high electronics flowability, and the reduction potential of pyridine groups is lower than the pure aromatic series of analog structure, be more conducive to accept electronics, the pyridyl group of electron deficiency is incorporated into into the both sides to the indenofluorene group, can improve the charge transporting ability of this compounds, so that it has good electronic transmission performance.The phenyl group that the while pyridyl connects, thus xenyl group and naphthyl group are except the molecular weight that can improve this compounds improves its second-order transition temperature; Also can so that this compounds has to a certain degree distortion at space multistory, improve its film-forming properties.In addition, the symmetry of molecular structure can increase the regularity of molecular stacks, has also improved to a certain extent carrier mobility.Upward introduce fatty carbon chains and improved on the one hand the solvability of compound in organic solvent for 6 and 12 of indenofluorene; Also increased on the other hand the film-forming properties of compound when vacuum evaporation.Therefore compound of the present invention has higher electronic transmission performance, and good film-forming property at room temperature has higher stability, and applied device also has higher stability.
The present invention develops a kind of novel organic materials, and preparation is simple and this material has good thermostability, and high electronic mobility can be used as electron transfer layer in organic electroluminescence device.
The present invention discloses a class novel cpd, and its general structure is as follows:
Wherein Ar is selected from phenyl group, xenyl group or naphthyl group, and R is the alkyl of carbonatoms 1-6.Wherein R can be methyl, ethyl, propyl group, sec.-propyl, butyl, isobutyl-, n-pentyl or n-hexyl.The concrete structure of Ar among the following formula I is selected from Formula Il, III, IV, V or VI:
